This cup leaks straight out of the box. Waste of money. The mixer blade is very delicate and will break easily and even warns this in the information on the box. It also tells you not to get the motor at the bottom wet. It leaks through the middle right onto the motor. I just got this and It leaks and is way to delicate. Im sure due to these problems mine will be broken soon. Dont waste your money. I thought it seemed like a good idea but the leaking aspect makes it not worth the purchase.

First one I bought I really like, lasted about 6 months before it cracked on the base of the glass right by the mixer blade and started leaking quickly onto the motor. Thought maybe I was cleaning it in too hot of water so I ordered two more. Second one cracked on first use in the same spot as the first, third seems to be working for now. I think they really don't like the mixing liquid to be too cold, I was using almond milk straight from the fridge. If 2 of the 3 hadn't cracked so easily it would be a 5 star product.
